Cognos 8 Drill Through From Pdf Within Email Possible?

We are unable to drill-through from a PDF report attached to an email. When running a report to be mailed as a PDF attachement, opening the PDF from an email client and clicking a drill through option presents the following error within Adobe Reader "An error occured during the submit process. Unknown failure."
However, when running the report within the Cognos enviornment and drilling through, it works fine.

Has anyone been able to get drill-through from PDF within an email working or is drill-through only possible if running reports within the Cognos enviornment?
Cheers.

Take a few minutes and think about it.
You run a report and attach it to an email.
The recipient opens the email and then opens the attachment (say a PDF).
How would it be possible for a drill thru from the PDF to work when the recipient is NOT connected to any cognos environment.
It is not possible to have a working drill thru when the report is attached.
If the report is sent as a link, then clicking the link brings the user into the cognos environment and now when they view the pdf, the user is in Cognos and then the drill thrus will work.
Of course, this also requires that the user opening the email with the link can connect to the cognos environment. If they are outside your network, then they won't be able to view the report (as a link).

it is been a while Mark.
so far I know this is possible "is drill-through only possible if running reports within the Cognos enviornment?"
once u attach pdf with email pdf become static then lt lose is the html connection string so that why it is showing the error msg. that is the only reason when we burst the drill thru report we have only send the link to the users.

You cannot do this, once the report is in PDF, and emailed then unless you know the exact URL rot the report you cannot open a drill down from it. This is also a problem if you create a report and run interactively as PDF and then try to drill down. You also do not have this functionality on Excel. To get this functionality you need to attach a link to the HTML version of the report.
